gaoThe Government Accountability Office will investigate PR and advertising spending after a request from Senate Budget Committee Chair Mike Enzi.

Enzi, in a Feb. 5 letter to GAO Comptroller General Gene Dodaro, noted "federal resources dedicated to public relations activities is largely unknown," pointing to a Congressional Research Service estimate of $892.5M in fiscal 2013.

Enzi had previously requested an accounting from the Office of Management and Budget but the OMB said it could not process the request.

The senator's GAO request is twofold: 1) spending across the federal goverment on PR activities, including contracts and internal agency support; and 2) federal agencies spending the most on PR and for what purpose.
